Main PCB Disassembly Procedures 
This section describes the items that may be removed/replaced from the main 
PCB assembly of the monitor. The main PCB assembly is separable from the 
front case assembly. 
Step 1. First separate the front and rear assemblies as described in the section 
“Separation of Front and Rear Case Assemblies” on page 45.
Step 2. Then remove the main PCB assembly from the front case assembly, as 
described on page 49.
Removing the Side Panel and Side Connector PCB   
Step 1. Use needle-nose pliers or a Tinnerman tool to remove the two 
Tinnerman fasteners securing the white plastic side panel to the 
underside of the main PCB.
Step 2. The side panel is attached by screws to the side connector PCB. 
Remove this assembly from the main PCB by pulling it straight up, 
disconnecting the multipin connector at J3 on the main PCB.

Step 3. Use a Phillips-head screwdriver to remove the six screws that secure the 
side panel to the socket surrounds. Access to the screws is gained 
through the holes in the side connector PCB.
Step 4. Remove the side panel from the side connector PCB.

Replacing the Side Panel/Side Connector PCB  
Step 1. Place the side panel on the side connector PCB so that the sockets on 
the side connector PCB fit the holes in the side panel.
Step 2. Using a Phillips-head screwdriver, fasten the side connector PCB to 
the side panel using the six screws.
Step 3. Align the studs on the bottom of the side panel with the holes on the 
main PCB. Also align the pins at J3 on the main PCB with the 
corresponding multipin connector on the side connector PCB.
Step 4. Push down until the pins at J3 on the main PCB are fully mated with 
the multipin connector on the side connector assembly. There should 
be no gap between the bottom of the side connector PCB and the 
main PCB. Ensure that the side connector PCB is perpendicular to the 
main PCB.
Step 5. From underneath the main PCB, fit a new Tinnerman nut to each of 
the two side panel studs located in the holes on the main PCB. Ensure 
that the side panel PCB remains perpendicular to the main PCB 
surface, and that the side panel is held firmly by the Tinnerman nuts.
